	<p>内置插件包括生成器和转化器。</p>
<p>每个插件都可以通过如下两种方式触发：</p>
<ul>
<li>
<p>通过 kustomization 文件的字段隐式触发插件，例如 <code>AnnotationsTransformer</code> 就是由 <code>commonAnnotations</code> 字段触发的。</p>
</li>
<li>
<p>通过 <code>generators</code> 或 <code>transformers</code> 字段显式触发插件（通过指定插件的配置文件）。</p>
</li>
</ul>
<p>直接使用 <code>kustomization.yaml</code> 文件中的字段比如 <code>commonLables</code>、<code>commonAnnotation</code> 他们可以修改一些默认的字段，如果用户想要添加或减少能被 <code>commonLabel</code> 所修改的字段，则不是很容易做到；而使用 <code>transformers</code> 的话，用户可以指定哪些字段能被修改，而不受默认值的影响。</p>

<h4 id="字段名称configmapgenerator">字段名称：<code>configMapGenerator</code></h4>
<p>列表中的每个条目都将生成一个 ConfigMap （合计可以生成 n 个 ConfigMap）。</p>
<p>下面的示例会生成 3 个ConfigMap：第一个带有给定文件的名称和内容，第二个将在 data 中添加 key/value，第三个通过 <code>options</code> 为单个 ConfigMap 设置注释和标签。</p>
<p>每个 configMapGenerator 项均接受的参数 <code>behavior: [create|replace|merge]</code>，这个参数允许修改或替换父级现有的 configMap。</p>
<p>此外，每个条目都有一个 <code>options</code> 字段，该字段具有与 kustomization 文件的 <code>generatorOptions</code> 字段相同的子字段。</p>
<p><code>options</code> 字段允许用户为生成的实例添加标签和（或）注释，或者分别禁用该实例名称的哈希后缀。此处添加的标签和注释不会被 kustomization 文件 <code>generatorOptions</code> 字段关联的全局选项覆盖。但是如果全局 <code>generatorOptions</code> 字段指定 <code>disableNameSuffixHash: true</code>，其他 <code>options</code> 的设置将无法将其覆盖。</p>

<p>此列表中的每个条目都应可以解析为 <a href="https://github.com/kubernetes/community/blob/master/contributors/devel/sig-api-machinery/strategic-merge-patch.md">StrategicMergePatch</a>.</p>
<p>这些（也可能是部分的）资源文件中的 name 必须与已经通过 <code>resources</code> 加载的 name 字段匹配，或者通过 <code>bases</code> 中的 name 字段匹配。这些条目将用于 <em>patch</em>（修改）已知资源。</p>
<p>推荐使用小的 patches，例如：修改内存的 request/limit，更改 ConfigMap 中的 env 变量等。小的 patches 易于维护和查看，并且易于在 overlays 中混合使用。</p>
